“…KDR is mainly expressed in the vascular endothelium of the theca layer in chicken follicles. KDR might be the most important receptor which is involved in VEGF-induced angiogenesis [70][71][72]. FLT1 can regulate the VEGF activity via interacting with VEGF and making it less available to KDR [73].…”

Background: Changshun green-shell laying hen with strong broodiness is a Chinese indigenous chicken breed. Little is known about the mechanisms responsible for ovary development of Changshun green-shell laying hens from egg-laying period (LP) to incubation period (BP). Here, RNA sequencing (RNA-seq) of ovaries from Changshun hens in LP and BP was performed to identify candidate genes and pathways associated with broodiness. Results: We identified 1650 differently expressed genes (DEGs), including 429 up-regulated and 1221 down-regulated DEGs, in chicken ovaries between LP and BP groups. GO and KEGG analysis further revealed that these DEGs were mainly involved in the pathways related to follicle development in chicken ovaries, including focal adhesion, MAPK signaling pathway, and FoxO signaling pathway, and vascular smooth muscle contraction, ECM-receptor interaction, and GnRH signaling pathway were down-regulated in incubating ovaries. Eight candidate genes (EGFR, VEGFRKDRL, FLT1, KDR, PDGFRA, TEK, KIT and FGFR3) related to angiogenesis, folliculogenesis, steroidogenesis and oogenesis in ovaries were suggested to play important roles in the ovarian development of Changshun hens during the transition from LP to BP. Conclusions: We discovered critical genes and pathways which is closely associated with ovary development in incubating chickens, indicating the complexity of reproductive behaviour of different chicken breeds.

“…Among the main diets of Bar-headed Geese, the Asteraceae family is the only one that we cannot determine its specific species, which is mainly composed of vegetables, medicinal plants, and ornamental plants. A.sinensis is commonly used as a traditional medicinal herb or a food/dietary supplement in Asia, Europe, and North America, has the effects of tonifying blood and activating blood circulation ( Ping et al, 2023 ). A. philoxeroides is an invasive alien plant with antibacterial and antiviral functions ( Rattanathongkom et al, 2009 ; Peng et al, 2021 ).…”

IntroductionGut microbiota of wild birds are affected by many factors, and host genetic background and diet are considered to be two important factors affecting their structure and function.MethodsIn order to clarify how these two factors influence the gut microbiota, this study selected the sympatric and closely related and similar-sized Black-necked Crane (Grus nigricollis) and Common Crane (Grus grus), as well as the distantly related and significantly different-sized Bar-headed Goose (Anser indicus). The fecal samples identified using sanger sequencing as the above three bird species were subjected to high-throughput sequencing of rbcL gene and 16S rRNA gene to identify the feeding types phytophagous food and gut microbiota.ResultsThe results showed significant differences in food diversity between black-necked cranes and Common Cranes, but no significant differences in gut microbiota, Potatoes accounted for approximately 50% of their diets. Bar-headed Geese mainly feed on medicinal plants such as Angelica sinensis, Alternanthera philoxeroides, and Ranunculus repens. Black-necked cranes and Common Cranes, which have a high-starch diet, have a similar degree of enrichment in metabolism and synthesis functions, which is significantly different from Bar-headed Geese with a high-fiber diet. The differences in metabolic pathways among the three bird species are driven by food. The feeding of medicinal plants promotes the health of Bar-headed Geese, indicating that food influences the functional pathways of gut microbiota. Spearman analysis showed that there were few gut microbiota related to food, but almost all metabolic pathways were related to food.ConclusionThe host genetic background is the dominant factor determining the composition of the microbiota. Monitoring the changes in gut microbiota and feeding types of wild birds through bird feces is of great reference value for the conservation of other endangered species.
